LNU2H272MTEG

The LNU2H272MTEG is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series, specified for high‑voltage power electronics. It provides 2700 µF capacitance at a 500 V rating with a polarized radial can and stud‑bolt mounting for secure power‑stage installation.

Designed for industrial power supplies and inverter circuitry, this capacitor offers high‑voltage capability, a long high‑temperature load life, and high‑frequency charge/discharge endurance suited to regenerative drives and inverter applications.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with ±20% tolerance and a rated voltage of 500 V (series rated range up to DC 525 V).
• High‑temperature endurance — Rated for operation from −40 °C to +105 °C with a defined load life of 5000 hours when subjected to rated ripple current at 105 °C.
• High ripple and high‑frequency support — Ripple current capability of 9.6 A at 120 Hz and 13.44 A at 10 kHz, enabling use with high‑frequency regenerative voltages and rapid charge/discharge cycles.
• Robust endurance & charge/discharge life — Specified to meet performance criteria after 50 million charge/discharge cycles (ΔV = rated − 0.3 V, 3 Hz), maintaining capacitance, tan δ, and leakage limits.
• Leakage, insulation and voltage proof — Leakage current limited to 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at 20 °C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality.
• Package & mounting — Radial can with screw terminals and stud/bolt mount (nominal bolt M5). Physical size: length 13.5 cm × diameter 6.35 cm; polarized configuration for power applications.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting modern environmental requirements.

Typical Applications

• Industrial power supplies — Bulk energy storage and DC link smoothing in industrial inverter power supplies where high voltage and long life at elevated temperatures are required.
• Inverter circuitry — DC link and filtering for motor inverters, benefiting from the capacitor’s high ripple current and high‑frequency performance.
• Regenerative drives / AC servomotors — Handling high‑frequency regenerative voltages and rapid charge/discharge events in motor drive systems.
• High‑frequency power electronics — Applications that impose fast charge/discharge loading and require a durable electrolytic solution with defined ripple ratings and endurance.

Unique Advantages

• High‑voltage capability in a compact package: 500 V rated (series up to 525 V) provides DC link capability while maintaining a smaller footprint compared with some legacy high‑voltage types.
• Engineered for elevated temperatures: 5000 hours load life at 105 °C under rated ripple current supports reliable operation in hot industrial environments.
• High ripple and frequency performance: Specified ripple currents at both 120 Hz and 10 kHz enable use in both mains‑frequency and high‑frequency converter topologies.
• Durable charge/discharge endurance: Designed to retain capacitance and leakage characteristics after extensive charge/discharge cycling, suitable for applications with frequent energy transfer.
• Robust safety margins: Clear insulation resistance, leakage current limits, and voltage‑proof testing (AC 2500 V, 1 min) provide measurable safety and reliability parameters for power designs.
• RoHS compliance: Meets current environmental directives for restricted substances.
